About this interactive

From the lesson and its Pi demo: - **A lease ties up an address** until it runs out, even after the device has left. Where many devices come and go and addresses run short, a long lease can exhaust the scope, so shorten it: the lesson's college went from a day to an hour. - **Every client renews at half its lease**, so short leases mean more renewal traffic. Where the same devices stay and the scope has far more addresses than clients, a longer lease means less checking in. The demo's choice: about 12 hours, a working day, so an address frees up overnight. - **No single right length:** it depends on how fast devices turn over and how many addresses you have.
